Dhammapada · 20.17
Etamatthavasaṃ ñatvā, paṇḍito sīlasaṃvuto;Nibbānagamanaṃ maggaṃ, khippameva visodhaye.
Etamatthavasam natva, pandito silasamvuto; Nibbanagamanam maggam, khippameva visodhaye.
Knowing this purpose, the wise one, restrained by virtue, should swiftly purify the path that leads to Nibbana.
